Ang '''Ikaapat na Krusada''' (1202–1204) ay orihinal na nilayon upang sakupin ang kinokontrol ng mga Muslim na siyudad ng Herusalem sa pamamagitan ng pananakop sa pamamagitan ng Ehipto. Sa halip nito, noong Abril 1204, sinakop ng mga nagkrusadang Europeo ang siyudad na [[Silangang Ortodokso|Silangang Kristiyano]] ng [[Constantinople]] na kabisera ng [[Silanganing Imperyo Romano]]. Ito ay nakikita na huling mga akto ng [[Schismo ng Silangan-Kanlurarn]] sa pagitain ng Simbahang [[Silangang Ortodokso]] at [[Simbahang Katoliko Romano]] at isang mahalagang pangyayari sa pagbagsak ng Imperyo at [[Kristiyano]] sa Silangan. Itinatag ng mga nagkrusada ang [[Imperyong Latin]](1204–1261) at [[Latinokratia|iba pang mga estadong Latin]] sa mga lupaing Byzantine na kanilang sinakop. Ang pagsalungat ng Byzantine sa mga hindi nasakop na bahagi ng imperyo gaya ng [[Nicaea]], [[Trebizond]], at [[Epirus]] ay sa huli nagpalaya sa kabisera at nagpabagsak sa mga [[estado ng nagkrusada]].
